Buying wheels - confused by off-set, spacers, etc...

I thought I was cool. Just going to buy some 9&11x17 for my '79 930 from either Kodiak, Fiske, CCW, etc. Then I started searching past posts and figured out I understand nothing... so, if anyone wants to help, I'd greatly appreciate it!!

Q1 - 11 vs. 11.5 - I'm guessing I'll run 315x35x17. Is one width wheel size better than another - or why choose one over the other? Will 11.5 cause any clearance issues?

Q2 - Hub width - does it vary among early & later 930's? Does it matter?

Q3 - Spacers - I believe pre-'80 had one size and post-'79 had another? True for front & back or just front? Does it matter?

Q4 - Spacers pt.II - Should I run with or without factory spacers? Or, is it just a personal preference based on aesthetics (i.e. deeper dish w/o spacers)?

Q5 - The numbers - Should I specify the back spacing/offset to the wheel company? Or trust they know what's needed to be known for my specific application? Are there generally accepted "best" offset/backspacing for a '79?

I hate being ignorant!

Thanks,
Skip
